A) \[101.73\times {{10}^{-4}}\]dyne
B) \[101.73\times {{10}^{-5}}\]dyne
C) \[16.95\times {{10}^{-5}}\]dyne
D) \[16.95\times {{10}^{-4}}\]dyne
E) \[1.6\times {{10}^{-4}}\]dyne
Correct Answer: A
Solution :
From Stokes law \[F=6\pi \eta rv\] \[F=6\pi \times 18\times {{10}^{-5}}\times \left( \frac{0.3}{10} \right)\times 100\,\text{dyne}\] \[F=0.01073\,\,\text{dyne}\] \[F=101.73\times {{10}^{-4}}\,\text{dyne}\]You need to login to perform this action.
